Specific embodiment

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.

In the specific implementation, ASON network described in the embodiment of the present invention is a kind of standardized intelligent optical transfer network, The mainstream technology for the next-generation optical-fiber network being widely believed that.LSP is packet by a series of in the transmission of label switched mechanism It jumps station and is formed by transmission channel.One label switched path can flexibly be selected according to conventional routing mechanism or configuration With.

Currently with the development of transmission network, network survivability becomes the operations such as current network design, operation and maintenance The middle important content for needing to pay close attention to, the protection of high efficient and flexible and recovery ways become the prerequisite important spy of ASON network Sign.Protection is complicated such as ODUK looped network protection simply such as 1+1 protection in plate usually using pre-assigned capacity between network element (ODUK Spring) protection.Network recovery then usually utilizes available any capacity between network element.For example, the business of high priority When recovery, using random capacity available between network element, the capacity including distributing to low priority traffice originally.When the road of business When by failing, the substitution of network Automatic-searching failure routing is routed, and recovery algorithms are identical as network routing algorithm.Use recovery When mode, network must advance for a part of idling-resource, for using when business heavy-route.

ASON network still can use traditional protected mode, such as ODUK Spring.Recovery in ASON network uses Heavy-route mode.When LSP is interrupted, first node calculates the optimal path of a business recovery, is then set up by signaling One new LSP, transmits business by new LSP.In actual user's network, for important business, user is held with strange land Calamity backup guarantees service reliability, such as Fig. 1 with ASON Dynamic- Recovery ability.Scene described in Fig. 1 carrys out ASON network It says, its operating path (LSP1 in corresponding diagram 1) of same business and Protection path (LSP2 of corresponding diagram 1) have different respectively First node and end-node.Distributed ASON technology respectively as an ASON service management, simultaneously provides this two paths The association ability of this two business is modeled as a business.Service creation in the prior art is described below in conjunction with Fig. 2 Realization process.

It referring to fig. 2, is prior art service creation implementation process schematic diagram.The service creation stream of prior art Journey comprising steps of

1, the main LSP of user configuration (LSP1).

The configuration information of the main LSP (i.e. LSP1) of creation correlation protection business can be arranged in user in network management, to pass through net Pipe triggers network element 1 and creates LSP1.Wherein, above-mentioned LSP1 is the operating path of ASON business.

2, network management creates LSP1.

Network management can obtain the configuration information of the LSP1 of user configuration, so trigger network element 1 create NE on LSP1.

3, user configuration LSP2.

The corresponding Protection path of operating path of creation correlation protection business can be also arranged (also referred to as work in user in network management Make path) configuration information of LSP2, triggers network element 2 to pass through network management and creates LSP2.Wherein, above-mentioned LSP2 is operating path The corresponding Protection path of LSP1.

4, network management creates LSP2.

Network management can obtain the configuration information of the LSP2 of user configuration, so trigger network element 2 create NE on LSP2.

5, the active and standby associated services of user setting.

User can set LSP1 and LSP2 to associated services, and user can set the incidence relation of LSP1 and LSP2.Wherein, The incidence relation of above-mentioned LSP1 and LSP2 is the related information of user terminal visible LSP1 and LSP2, and network element 1 and network element 2 need logical Cross the routing information that communication protocol obtains other side.

6, the association of LSP1 and LSP2 is arranged in network management triggering network element 1.

7, the association of LSP1 and LSP2 is arranged in network management triggering network element 2.

Network management triggers network element 1 and the association of LSP1 and LSP2 is arranged in network element 2, and the business of LSP1 and the business of LSP2 are arranged For associated services.Network element 1 and network element 2 can obtain the routing information of other side by communication protocol.However, even if network element 1 and network element 2 When incidence relation provided with LSP1 and LSP2, network element 1 and network element 2 carry out service creation, or separates oneself and calculates path, So that the service path that network element 1 and 2 separate computations of network element obtain may not be optimal service path, the creation effect of service path Fruit is bad.

8, there is traffic failure simultaneously in network element 1 and network element 2.

When the corresponding LSP1 of network element 1 breaks down, network element 1 can determine that its business breaks down, and then can be on network management Report traffic failure；When the corresponding LSP2 of network element 2 breaks down, network element 2 can determine its business processing failure, and then can be to network management Report traffic failure.

9, the traffic failure of network element 1 is shown.

10, the traffic failure of network element 2 is shown.

After network management receives the traffic failure that network element 1 and network element 2 report, then can traffic failure to network element 1 and network element 2 into Row display, is presented to the user.The traffic failure that user can show according to network management determines service condition, and then can be according to its setting The incidence relation of active and standby associated services determines the on off operating mode of each business, and then may specify that single business carries out the behaviour such as heavy-route Make.

11, network element 1 carries out business heavy-route.

12, network element 2 carries out business heavy-route.

In the specific implementation, network element 1 can be arranged according to network management if traffic failure occurs in above-mentioned LSP1 when needing to carry out heavy-route The routing information for the service path (LSP2) that the network element 2 obtained when LSP1 is associated with LSP2 creates, calculates the heavy-route road of LSP1 Diameter.If traffic failure occurs in network element 1, when needing to carry out business heavy-route, there is traffic failure simultaneously in the LSP2 on network element 2, If LSP1 and LSP2 is there are intersection, and intersection breaks down, and LSP2 and LSP1 carry out heavy-route simultaneously.Due to net The priority that member carries out service path heavy-route, which is higher than, notifies that, to the priority of other side's network element, network element is preferential for service path information Service path heavy-route is carried out, then the information of service path is notified into other side's network element, so that network element obtains the service path of other side Not in time, network element carries out the last state that can not consider the service path of other side when service path heavy-route in time to information.Work as net Member 1 and network element 2 carry out heavy-route path calculating when, due to obtain other side routing information not in time, network element 1 and network element 2 can It can calculate onto identical path, so that the heavy-route path computing of LSP1 and LSP2 is inaccurate or is unable to reach two business Path is optimal simultaneously, and heavy-route is ineffective, and business survivability reduces etc..

Can not be using two service paths as a service management for operations such as prior art service creations, it can not The problems such as realizing the timely sharing of service path information, the embodiment of the invention provides a kind of service protecting methods, can pass through control Device processed carries out the associate management of service path, and the calculating of service path is realized by controller, can support the state of service path It is shared, business survivability is promoted, the complexity of the operations such as business heavy-route is reduced.

The embodiment of the present invention can by creating a kind of ASON business on the controller, specifically, in embodiments of the present invention, The ASON business of controller creation can be ASON diamond grade business.It below will be by taking ASON diamond grade business as an example, to of the invention real The service protecting method for applying example offer is specifically described.Controller produces the service path of two ASON business, by upper The service path of two ASON business is stated to transmit ASON business information, passes through the service path and industry created on operation controller Business ID come trigger network element create NE on service path or heavy-route service path or optimization service path.Work as network element On when there is traffic failure, network element can send alarm request or heavy-route request to controller and be managed, and then can be real The state tying of existing service path.The embodiment of the present invention can create new diamond grade business, the settable multiple source nodes of business and Multiple destination nodes, in the same node, identical veneer port and channel is can be used in operating path and Protection path, can also be made With different veneer ports and channel.That is, the diamond grade business that method described in the embodiment of the present invention is created may include more The diamond grade business of kind type of service, such as with the first type of service with end, that is, identical source node (being also first node) and phase Same destination node (being also end-node), or the type of service with first different end, that is, identical source node and different destination nodes, Or the different first type of service with end, that is, the type of service at different source nodes and identical destination node or the different end different head, That is, different source nodes and different destination nodes.

It is specifically retouched below in conjunction with method and device of the Fig. 1 to Figure 11 to service protection provided in an embodiment of the present invention It states.

It is the first embodiment flow diagram of the method for service protection provided in an embodiment of the present invention referring to Fig. 3.This hair The method of service protection described in bright embodiment comprising steps of

S101, controller create the first label switching path LSP and the 2nd LSP of ASON business, and the first LSP is work Make path, the 2nd LSP is Protection path.

In the specific implementation, controller can create an ASON diamond grade business according to user configuration first when service creation. Wherein, the ASON diamond grade business that above-mentioned ASON diamond grade business concretely enhances, controller can pass through above-mentioned ASON diamond The traffic ID of grade business realizes the associate management to business on different LSP, realizes that the status information of associated services is shared.Controller After creating ASON diamond grade business, two LSP of above-mentioned ASON business, including the first LSP and the 2nd LSP are produced, In, the first LSP is operating path, and the 2nd LSP is Protection path, transmits ASON business information by two LSP of generation.

Further, when the ASON diamond grade business of controller creation enhancing, it can receive the user configuration that network management is sent, In, above-mentioned user configuration may include multiple source nodes and multiple destination nodes, i.e. at least one source node and at least one destination node. Wherein, the source node of above-mentioned user configuration can be the same source node, can also be different source nodes, the place of above-mentioned user configuration Node can be the same destination node, can also be different destination nodes.The industry that controller is generated according to above-mentioned source node and destination node Business can include: with first with end, perhaps with the first different end perhaps different first business with the types of service such as end or different different end head.Control It may include that identical source node (is also head in the ASON diamond grade business that device processed is created according to above-mentioned source node and above-mentioned destination node Node) and identical destination node (being also end-node) two service paths or identical source node and different destination nodes Two service paths perhaps different source node and identical destination node two service paths or different source nodes With two service paths of different destination nodes.

In the specific implementation, the user configuration that controller can be sent according to above-mentioned network management generates the ASON diamond grade industry of enhancing Business, it is also necessary to the service path for the LSP that two are separated from each other is calculated according to current network environment.In the specific implementation, as schemed 4, cost10 and cost100 described in figure are that link cost can carry out link cost tired when controller calculates path Add, the smallest path of number added up on path is chosen to be destination path.Wherein, above-mentioned cost10 and cost100 is only chain One example of road cost, specific value can be determining according to actual scene, herein with no restrictions.In the specific implementation, controller meter When calculating two service paths of ASON business, can be separated from each other first according to operating path and Protection path (i.e. Protection path and Operating path is not overlapped) principle, determine two service paths in conjunction with the link cost on service path, then pass through link cost Calculating two service paths are finally calculated.Specifically, if controller only considers a paths when calculating service path, Calculated path may be A-B-C-D (number on path is cost10+cost10+cost10) to controller for the first time, this When the path either A-B-D (number on path is cost10+cost100) that calculates of the controller second or (road A-C-D Number on diameter is cost10+cost100) all will there are link repetitions with the first paths, i.e., the path that calculates for the first time and Second of path calculated will be unable to separate.So in order to which the service path of two separation is calculated, controller needs root Two paths, the primary path-line for determining two paths are considered simultaneously according to network environment (such as state of each intelligent net element) Road finally calculates two optimal service paths of LSP further according to the link cost on path lines.

The configuration information of first LSP is handed down to the first network element by S102, the controller, by the 2nd LSP's Configuration information is handed down to the second network element, triggers first network element and creates the first LSP, triggers second network element and creates institute State the 2nd LSP.

In some possible embodiments, controller according to user configuration generate enhancing ASON diamond grade business (with Lower abbreviation ASON business) and after generating two LSP of ASON business, then the configuration information of above-mentioned two LSP is handed down to two A network element, triggering network element create NE on LSP.Further, in embodiments of the present invention, above-mentioned two LSP match confidence The traffic ID of above-mentioned ASON business is carried in breath.Above-mentioned traffic ID can be carried and is handed down in the configuration information of LSP by controller Network element, triggering network element create NE on LSP.Specifically, in two articles of LSP that controller can be generated the first LSP (such as Operating path) configuration information (traffic ID comprising ASON business) be handed down to the first network element, the first network element of triggering creation first LSP on network element.Further, in two articles of LSP that controller can also be generated another article of LSP (that is, the 2nd LSP, such as The corresponding Protection path of above-mentioned operating path) configuration information (traffic ID comprising ASON business) be handed down to the second network element, touch Send out the LSP on the second network element the second network element of creation.It, then can root after first network element receives the configuration information of above-mentioned first LSP According to above-mentioned configuration information and traffic ID create NE on the first LSP；Second network element receives the configuration information of above-mentioned 2nd LSP Later, then the 2nd LSP on being created NE according to above-mentioned configuration information and traffic ID.

In some possible embodiments, the configuration information of the first LSP is handed down to the first network element by controller, triggering the One network element creates the first LSP, and the configuration information of the 2nd LSP is handed down to the second network element, the second network element of triggering create the 2nd LSP it Afterwards, the business carried in the configuration information of the traffic ID and the 2nd LSP that can also carry in the configuration information by above-mentioned first LSP ID is associated with the first LSP and the 2nd LSP, and then can be associated management to the first LSP and the 2nd LSP.For example, passing through the first LSP The traffic ID carried in the fault message that corresponding first network element is sent searches the 2nd LSP etc..
